lower than the actual altitude above sea level.
The main difference between altimeter and cabin altimeter is the place where they take their pressure: Altimeter takes the pressure from static ports, while cabin altimeter takes it's pressure from the cabin.
There isn't one because it is a noun
A compass or a GPS system would do the trick. An altimeter will indicate whether you are maintaining, losing, or gaining altitude.
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
true altitude at field elevation.
My handheld GPS instrument has a barometric altimeter in it also.
My GPS instrument contains a barometric altimeter.
Aerodynamics refer to the physical forces of the environment and the design of the aircraft and encompass lift, drag, and thrust conditions. Avionics refer to the instruments which pass information to the pilot and involve navigation, radio, altimeter, airspeed, etc.
My wristwatch has an altimeter, which as a backpacker, I find very useful.
An altimeter is a piece of apparatus which measures someone's altitude.
